ASH-SIFTER.

Specification of Letters `Patent.

Patented J une d, 1918.

To all 'whom t may concern.'

Be it known that I, I-IIRsH BURNsToNE, a

citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Ash-Sifters, of which the following is a specification.

, This invention relates to an ash sifter of novel construction by means of which ashes may be effectively sifted in a dust proof manner.

In the accompanying drawing:

Figure 1 is a longitudinal section of an ash sifter embodying my invention;

Fig. 2, a plan with the cover removed, and P Fig. 3, a horizontal section on line 3 3 The device comprises a tapering shell 1, which is open at the bottom, and is adapted to be closed at the top by a cover 2. Through shell l, extends axially, a shaft 3, journaled in an upper strap 4 and a lower strap 5, said straps passing diametrically across the shell. The upper strap 4, is secured at its ends to a circular band or hoop 6,l that extends along the inner side of the shell, while the lower strap 5, is secured to the latter by means of flanges 7, which are riveted to the shell` as at 8. Within shell 1 is centered a coniform screen 9, which tapers from top to bottom, and is interposed at its upper edge between shell 1 and hoop 6, so as to be held rmly in position. .The lower end or apex of the screen is raised a distance oft' the lower end of the shell, and is here furnished with a tubular bearing 10 for the accommodation of shaft 3, which is centered within the screen.

Upon the shaft is fast a stirrer 11 which passes centrally through the screen and is formed of a coniform open Work blade which tapers from top to bottom, said blade comprising essentially a pair of converging Copies of this patent may be obtained for vc cents each,

end members and a plurality of spaced horizontal bars that connect said members.

Shaft 3 protrudes through an opening of cover 2 and may be coupled to a crank handle 12 for which purpose shaft3 has a squared end, that is removably received within a correspondingly squared socket depending from the handle. A bail 13 pivoted to ears 14, of shell 1 permits the ash sifter to be readily carried about.

In use, the device is mounted in a dust proof manner upon an ash can or similar container 15 by being projected with its lower end into a flanged opening 16 of the latter. The ashes are dumped into. screen 9, cover 2 is applied, and handle l2 is fitted to shaft 3. The finer particles of the ashes will during dumping, pass directly through the screen 9, and fall by gravity into the clearance 17 formed between the screen and shell, from which clearance they will descend into the ash can 15. Shaft 3 being now rotated, the remaining ashes will be- `come agitated by the stirrer which will also break up clinkers and larger lumps, the ashes thns released and broken up dropping through'the screen into the clearance 17 and thence into the can l5, in manner previously described. The coal retained by the screen may be dumped after the handle 12 and cover 2 have been removed.

I claim:

An ash sifter comprising a shell, an upper strap and a lower strap extending across the same, a band carrying the upper strap and extending along the inner side of the shell, a shaft journaled in the straps, a screen confined at its upper end between the shell and band, a bearing on the lower end of' the screen that engages the shaft, and a stirrer mounted on the shaft within the screen.
